Description

Communication method, communication device and electronic equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method, a communication apparatus, and an electronic device.

Background

In 5G, a cell primary and secondary Synchronization Signal (SS) is coupled with a Physical Broadcast Channel (PBCH), and the coupled Signal appears in the form of SS/PBCH resource blocks, which are abbreviated as SSBs. In a New Radio (NR) system, there are multiple waves (beams), each Beam being associated to one SSB. If a Physical Downlink Control Channel (PDCCH) of a System Information Block (SIB) 1 is a Search space (Search space) 0, then the Search space 0 is associated to each SSB.

The monitored slots (slots) are different for different SSBs. When different base stations transmit data, the beam directions are different. And, the PDCCH CORESET (CORESET is a set of physical resources (i.e. a specific region on the NR downlink resource grid) and a set of parameters for carrying PDCCH/DCI) monitored by each Search space also corresponds to a corresponding SSB Quasi-co-location (QCL). Therefore, when receiving the SIB, it needs to receive on the strongest SSB listening slot in order to obtain the best reception new energy.

In the prior art, when a device is in an idle (idle) state, the device usually enters a sleep state due to power consumption. When a device wakes up from a sleep state, the state of the SSB may change, which may result in failed reception of the SIB.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

In an actual application scenario, before and after the device is dormant, a frequency offset and a time offset may exist. For example, in a sleep state, the device typically shuts down the receiver and the high accuracy clock, maintains only a low accuracy clock, which has an error in itself, and a transition error with the high accuracy clock. Thus, a clock skew is introduced when the device is recovering from hibernation.

Further, in the sleep state, in order to save power, the device only receives a part of the SSB, so that the device cannot perform tracking calculation on frequency offset, time offset, and Automatic Gain Control (AGC). Therefore, the device cannot sense the frequency offset and the time offset change of the SSB before and after the device is dormant, and the device cannot correspondingly adjust the AGC. Thus, when the device directly follows the strongest SSB before the sleep state, a problem arises in that the reception of the SIB fails because the SSB change is ignored.

In order to solve the problem of SIB reception failure due to neglecting SSB change, an embodiment of the present application proposes a communication method. In the method of the embodiment of the present application, when the device is awakened from the sleep state, first SIB reception is performed along with the strongest SSB that was last confirmed before entering the sleep state, and if reception is successful, it indicates that the strongest SSB has not changed during the sleep process of the device, and then subsequent SIB reception may all follow the strongest SSB. If the reception fails, performing complete reception and measurement on the SSB to confirm the strongest SSB; and calculating the position of the search space 0 according to the confirmed strongest SSB so as to perform the second SIB reception after awakening.

FIG. 1 is a flow chart of a method according to an embodiment of the present application. Assuming that the strongest SSB last confirmed by device a before entering the sleep state is SSB0, when device a wakes up from the sleep state, the following steps as shown in fig. 1 are performed to receive the SIB:

step 110, after the current device is awakened from the sleep state, calculating the position of the search space 0 according to the SSB0 to perform the first SIB reception after the current equipment is awakened;

step 120, determining whether the decoding of the first SIB reception after the wake-up is successful;

step 130, when the decoding of the first SIB reception after the current awakening is successful, performing the subsequent SIB reception after the current awakening according to SSB 0;

step 140, when the decoding of the first SIB reception after this wake-up fails, performing complete reception and measurement on the SSB to confirm the strongest SSB1;

and 150, calculating the position of the search space 0 according to the SSB1 so as to receive the SIB for the second time after the current awakening.

According to the method of the embodiment of the application, after the first SIB reception fails, the SSB is completely received and measured to confirm the strongest SSB, so that the reception performance is improved as much as possible, and the success rate of SIB reception is greatly improved under the condition of a weak channel. Compared with the prior art, according to the method provided by the embodiment of the application, the success rate of SIB reception can be greatly improved.

Further, in step 150, when the decoding of the SIB reception for the second time after the current wake-up is successful, it indicates that the SSB1 is available. Therefore, after step 150, SSB1 can be used to continue subsequent SIB reception after the wake-up, so that there is no need to perform complete reception and measurement on SSBs again to confirm the strongest SSB, and system consumption is greatly reduced.

Further, in order to improve the success rate of SIB reception as much as possible and avoid SIB reception failure, in an embodiment of the present application, when the decoding of the SIB reception for the second time after the current wake-up in step 150 is successful, before performing SIB reception after the current wake-up each time, the SSB is completely received and measured to re-confirm the strongest SSB;

and calculating the position of the search space 0 according to the newly confirmed strongest SSB so as to receive the SIB after the current awakening.

Further, when it is determined in step 120 that the decoding of the first SIB reception after the current wake-up fails, it indicates that a frequency offset and a time offset exist in the sleep state. Therefore, in an embodiment of the present application, to improve the success rate of SIB reception, after the decoding of the first system information block reception after the current wake-up fails, frequency offset and time offset tracking are performed on the SSB.

Further, during the communication of the device, in a communication cycle, when the communication cycle is not completed, the device may enter a sleep state, and at this time, a time offset and a frequency offset caused by the sleep may affect data reception in the communication cycle. In view of the above situation, in an embodiment of the present application, when it is determined in step 120 that the decoding of the first SIB reception after the current wake-up fails, it indicates that entering the sleep state may affect the reception of the SIB, and therefore, the current device is prohibited from entering the sleep state in the current data communication period. Therefore, the dormancy time offset and the frequency offset can be effectively avoided, and the success rate of SIB receiving is effectively improved.

Correspondingly, when it is determined in step 120 that the decoding of the first SIB reception after the current wake-up is successful, it indicates that entering the sleep state does not affect the reception of the SIB, and therefore, the current device is allowed to enter the sleep state in the current data communication period. Therefore, the power consumption can be effectively reduced on the premise of not reducing the success rate of SIB receiving.

Further, in an embodiment of the present application, when it is determined in step 120 that the decoding of the first SIB reception after the current wake-up fails, it indicates that entering the sleep state affects the reception of the SIB, and therefore, after the current device enters the sleep state again and is woken up again, it is not necessary to continue to use the strongest SSB (for example, SSB 1) before the sleep to perform the SIB reception (it is determined that entering the sleep state affects the reception of the SIB, and the probability of failure of performing SIB reception using the strongest SSB before the sleep is higher), but rather, the SSB is directly and completely received and measured to determine the strongest SSB2; the search space 0 position is calculated from SSB2 for the first SIB reception after waking up again. Thus, not only is power consumption reduced (no attempt is made using SSB 1), but also the success rate of SIB reception is effectively improved.

Further, in the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by an accessing party. A digital device is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as ABEL (Advanced Boolean Expression Language), AHDL (alternate Hardware Description Language), traffic, CUPL (core universal Programming Language), HDCal, jhddl (Java Hardware Description Language), lava, lola, HDL, PALASM, rhyd (Hardware Description Language), and vhigh-Language (Hardware Description Language), which is currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

Therefore, based on the method provided by the embodiment of the present application, the present application also provides a communication device. Fig. 2 is a diagram illustrating an apparatus structure according to an embodiment of the present application, and as shown in fig. 2, a communication apparatus 200 includes:

a receiving module 210, configured to calculate, after the current device is awakened from the sleep state, a search space 0 position according to a strongest SSB last before the current sleep, so as to perform first system information block reception after the current awakening;

Specifically, the SSB measurement module 220 is further configured to perform frequency offset and time offset tracking on the SSB after the decoding received by the system information block for the first time after the wake-up is failed.
